The motor is the most expensive part of an ebike. It’s an electromechanical device that converts electrical energy into mechanical energy through rotational motion or linear motion, known as Linear Induction Motor (LIM). A motor can be made out of many parts, but the most basic is the stator. It provides a magnetic field that drives the armature or rotor. It’s also the static part of the motor, which houses the field windings and receives the electrical supply through its terminals.
